<script type="text/javascript">
    function custvisit(){
        $("#flag").val("cus");//把值这样放进去（String flag=super.getRequest().getParameter("flag");）才会取到值
    document.jsbsearch.action="<%=path%>/lzf/jobSearchAction!jobpage.action"; 
document.jsbsearch.submit(); 
        }
    function jobdetails(){
    if(!checkRadio()){
alert("请选择一条记录!");
return;
}
    var temp = $('input:radio:checked').val();
$("#procInsId").val(temp);
    document.jsbsearch.action="<%=path%>/lzf/jobSearchAction!jobdetails.action"; 
document.jsbsearch.submit(); 
        }

    </script>
